I have owned a pair of these since 2010 and wear them consistently for a variety of outdoor activities during the cold weather months. They have an awesome fit for any sort of active, outdoor sport and have held up great for how hard I have been on them. I climb in them, wear them under my fly fishing waders for extra warmth, backpack in them, and have worn them over my cycling shorts during the extra harsh rides. The only complaint I have with these pants is that they have a small hook on the front of the cuffs at the bottom to hook to boot laces. This is a great feature when you want it, but can be annoying when I'm using them for something other than hiking. Over all, though, definitely a solid purchase.
